Former Air Force UFO Study Director: UFOs Need to be Studied More

A retired colonel who ran Project Blue Book for 20 years says the phenomenon needs scientific investigation

Retired Col. Robert Friend, a former director of the Air Force's nearly 20-year UFO study, Project Blue Book, says that science should continue looking into the mystery of flying saucers.

Friend, assigned in 1958 to direct Blue Book, was charged with trying to determine if UFOs were a threat to national security and whether they could be of scientific interest.
